Metazoan parasites of Geophagus brasiliensis (Perciformes: Cichlidae) in Patos Lagoon, extreme south of Brazil.
This study has evaluated the parasitic fauna of 79 pearl cichlids (Geophagus brasiliensis) from the estuary of Patos Lagoon (31° 57' S and 52° 06' W), Rio Grande do Sul, Brazil, during the months of May and June in 2011 and 2012. All the hosts analyzed were infected with at least one species of parasite. A total of eleven metazoa were identified in 459 specimens collected. The trematode Austrod...
متن کاملSoluble malate dehydrogenase of Geophagus brasiliensis (Cichlidae, Perciformes): Isolated isoforms and kinetics properties
Kinetic properties and thermal stabilities of Geophagus brasiliensis skeletal muscle unfractionated malate dehydrogenase (MDH, EC 1.1.1.37) and its isolated isoforms were analyzed to examine a possible sMDH-B* locus duplication in a fixation process influenced by genetic drift. Two optimal pHs were detected: 7.5 for AB1 unfractionated muscle phenotype and its B1 isoform, and 8.0 for AB1B2 unfra...
متن کامل[The role of Ancyrocephalinae (Monogenea: Dactylogyridae), parasite of Geophagus brasiliensis (Pisces: Cichlidae), as an environmental indicator].
The variations in the parasite population of fishes may be indicative of environmental alterations. With the aim of studying the variation of the parasitism by Ancyrocephalinae in Geophagus brasiliensis, two reservoirs of distinct trophic characterizations (Juqueri - eutrophic and Jaguari - oligomesotrophic) were compared. The prevalence rates and intensity of infection of this parasite were me...
متن کاملCytogenetic characterization of Geophagus brasiliensis and two species of Gymnogeophagus (Cichlidae: Geophaginae) from Guaiba Lake, RS, Brazil.
The karyotypes of three species of fish of the Cichlidae family from the Forqueta river and several locations in Guaiba lake/RS (Brazil) were analyzed. All species presented 2n=48, while Gymnogeophagus gymnogenys showed two karyotypic formulae: 4m+44st-a with FN=52 and 6m+42st-a with FN=54. Gymnogeophagus labiatus presented 4m+4sm+40st-a and FN=56 and Geophagus brasiliensis 4sm+44st-a and FN=52...
متن کاملCARACTERIZAÇÃO DE UM NOVO COMPLEXO BIMETÁLICO DE Pd ( II ) CONTENDO
This article reports the synthesis and characterization of a new binuclear complex of palladium (II) containing the antibiotic oxytetracycline. The complex was characterized by the usual techniques of analysis. With respect to sites of coordination, the IR spectral data suggests the involvement the oxygen of the amide group and the oxygen of the neighbor hydroxyl group at ring A and to the carb...
